Greg, I always use Mason boxes. They are made in both deep and shallow. A true mason box has a lip across the top and bottom for securing the device. I mount them flush or out a little to allow for the stucco. If the stucco is to have styrofoam insulation behind it, then I fasten a handy box extension to it to make up the 1 to 1.5" difference.
Unfortunately, setting boxes in concrete/block/brick is a common thing where I live, I keep a box of Mason boxes on the truck, along with a box of rapid set mortar, and a box of 20 min drywall compound.
